.To all 2c/lam t may concern:

Be it known that l, dosnrn fi. MORIN, a citizen of the United States, and a resident of Newark, county of Essex, and State of New dersei have invented certain new and useful improvements in Carroting Machines,

t which the following is a speciiication.

This invention relates to ian improved machine which is designed to treat on skins, so that the proper amount of l Y; 'cal is supplied to the skin in the carrotv ion so that the tur is slicked down e surface, carroting of fur the 'skins at present d on' tahle, and a workman dips a brush in a chemical with which is treated, usually nitrate ot mercrushes the skin with a few movethe brush against and with the ection ci the fur, slicking it down with the last sweep or two of the hrush and piling the skins so treated before they are baked. defect in this method is that unless extreme care is used, which care is a rare quality in workmen of the type used in carroting, all ot the ur is not treated, and second, the amount of chemical applied is not easily gaged, since too much chemical will hurn the iur, and insutlicient chemical will harden the fur and will not give it the proper elting qualities.

The present invention is designed to provide a machine that assures the treatment of the entire skin, and is easily regulated so ythat the workmen attending the machine apply the proper amount of chemical t-o the skin, judging the amount by the size of the skin which is inserted in the machine.

rlhe invention is illustrated in the accompanying drawing, in which l show a ma- 'chine embodying my invention, Figure l losing a section through the machine. Fignre a is a side view of the machine, showing a gear connection between the various shafts. Figure 3 is a tace view of the brush and its associated rollers. Figure et is an enlarged sectional detail, showing a skin passing through the machine, and Figure 5 is a perspective or" a part of the means for feeding chemical from the tank to the brush.

'lhemachine comprises any suitable Storm of standard, and l show one consisting of the legs l@ which are long enough to support the table ll at the top, about waist-high ot a workman or at a slightly higher elevation,

the ice il 'supporting the brush l2 which,

in the term shown, is mounted on a shalt 13 and is driven hy suitable means, such as the pulley i4 and the helt l5.

lie-ans for supplying chemical, such a nitrate of mercury, is provided, and l show in the drawing a tank i5 which is disposed so that the liquid l? in the tank is loelow the hrush l2, so that the hrush does not come in contact withthe liquid, and the supply of liquid is therefore controlled. TFor this purpose show a supply roller 18 which is moi d so that is normally suspended in th^ uid i7 and is normally' idle, hut when moved-to Contact with the hru'sh l2 it is rotated hy the hrush, the supply roller heing freely revoluole, and it thus picks up enough liquid on its circumference to feed the hrush. The roller i3 is usually of wood, which is used on account of its lightweight.

l'n the drawing the means for 'suspending the supply roller consists of a pair of links i9 pivoted at their top ends, as at 20, to the side oit the machine, and having a handle 2l., l/Vhen the handle 21 is pushed in, the supply roller is pressed against the brush, and since the hrush is constantly rotating, the roller picks up enough liquid to supply the brush with the proper quantity.

it it `is desired to hold the roller in any desired position, such as, for instance, against the brush, a suitable holding means can he provided, such as the pin 22, over which any of the perfor-ations 23 in the handle 2l can he placed.

feed the skin to the lorush ll" mount a pair of feed rollers 24 and 25, mounted on their respective shafts 26 and 27 and having nieshed gears 23 and 29. @ne of these shafts is positively driven preferably from the shaft 13, and. .l illustrate the shatt 27 as heing driven through the gears 30 and 31 from the `gear 32 on the shaft l The gearing is proportioned so that the feeding of the skin 33 through the rollers is at a' speed slow enough to have the brush l2 give a wiping or slicking action on that part of the skin that is passing over the roller 24, the roller losing relatively small and thus bending the skin enough 'to spread the fur as it contacts with the brush, and then the hrush wipes or slicks the lEur in the direction ot its natural lie, andthe skin, passing through not too rapidly, permits all of its length to loe thus treated, El@

and since the brush and thefeed rollers are widerthan the average skin, the skin is treated for its whole width.

The skin has a tendency to wrap itself around the roller 24, and as it rides up it is brushed from the roller by a fending brush 34 which rotates in a direction opposite to thatof the roller 24, and in the illustration I show the shaft 35 of the fending brush 34 connectedby the gears 36 and 37 with the shaft 27. As the major portion of the skin emerges and passes upward from the roller 24 it falls over and is received on a suitable means, such as the conveyor belt 38 which is usually of rubber or heavy' fabric and is mounted on the pulleys 39 and 40, the pulley 40 being driven y suitable means, such as the belt 41 passing over pulleys 42 and over a pulley 43 on the shaft 13.

When the workman is using this machine, if it is a small skin he feeds it between the constantly rotating feed rollers 24 and 25, and pushes the handle 21 in and holds it until the skin has been gripped by the feed rollers, and when the skin is once gripped and is started on its way there has usually been enough' chemical supplied to the brush 12 to treat the skin. In the case of a larger skin, of course, the handle 21 is pushed in for a longer periodv of time. A workman soon becomes accustomed, when he feeds the skin with one hand, to push in the handle 21 with the other and gage the length of time that the'supply roller 18 should be in contact with the brush 12, according to the size of theskin that he is treating.

In this machine there is an economy in the chemical employed, in that it is only table, and the whole table becomes wet and l there is a waste of chemical.

I claim:

1. A carroting machine comprising a brush moving in one direction, a means for feeding a skin ,so that the fur is curved and spread when presented to the brush and at a slower speed than the speed of the brush, a tank for holding liquid, va supply roller in the liquid, and means for moving the roller to contact with the brush.

2. A carroting machine comprising a brush moving in one direction, a means for feeding a skin so that the fur is presented to the brush and at a slower speed than the speed ofthe brush, a tank for holding liquid, a supply roller, links for suspendingv the supply roller in the liquid, and a handle for swinging the links so that the supply roller is moved to contact with the brush.

3. A carroting machine comprising a rotary brush, a tank unde-r the brush,'a supply roller mounted so as to be in contact with liquid in the tank and to be moved in contact with the brush, a handle for ,moving the brush, and feed rollers closely adjacent to each other and adapted to feed a skin to the brush and to present the furry side of the skin to the'brush at va slower speed than that 4of the brush.

In'testimo-ny that I claim the foregoing, I have hereto set my hand, this 21st day of May, 1923. v

JOSEPH A. MORIN.
